Abstract: A network diagnostic device is disclosed that digitally samples the voltages on the cabling of the network (10), but does so at a much higher rate and with greater resolution than is required to minimally detect digital transmissions on the cabling. This sampling provides information on the analog characteristics of digital, noise, and interference signals on the network. Thus, network problems can be precisely diagnosed. The device includes a fast digitizer (120) with a long memory (128a, 128b) and a system processor (140) that statistically analyzes the signal events captured by the digitizer (120). The invention is also capable of performing time domain reflectometry (TDR) analysis of a functioning network. This is accomplished by placing (150) a TDR signal on the network surrounded by a transmission that the network devices will interpret as a broadcast diagnostic packet. This will cause the network nodes to ignore the transmission. The digitizer, however, is able to detect the networks' response to the TDR signal. Methods for identifying unknown network sources and Manchester decoding are also disclosed.

Abstract: A scalable distributed caching system on a network receives a
request for a data object from a user. The caching system carries out a
locator function that locates a directory cache for the object. The directory
cache stores a directory list that identifies the locations of object caches that
purport to store copies of the object requested by the user. The object
caches on the object directory list are polled, and in response send messages
to the cache that received the user request indicating if each object cache
stores a copy of the requested object. The receiving cache sends a message
requesting a copy of the object to the object cache that sent the message
first received by the receiving cache indicating that an object cache stores
the requested object. The object cache that sent the first received message
then sends a copy of the object to the receiving cache, which stores a copy
and then sends a copy to the user. The directory list for the object is then
updated by adding the network address of the receiving cache. Outdated
copies of objects stored on object caches are deleted in a distributed fashion
to maintain the coherence of the cached copies. This is further reinforced
by the association of time-to-live parameters with the each copy and each
object cache address on directory lists.

Abstract: A telephone system is disclosed establishing a link
over a packet-switched-network (16), such as the Internet,
between two telephone interfaces (10,20) by exchanging
network addresses. The addresses can include ATM addresses
to allow a virtual connection to be established between the
interfaces. The interfaces exchange speech data packets of
speech signals from a called party telephone and a calling
party telephone over the network. An interface converts the
speech signals of the parties into the speech data packets.
The system dynamically allocates network and interface
resources to complete the telephone call transaction. The
system provides a number of enhanced calling services not
normally available to PSTN subscribers including: message-delivery,
call-back, call-screening, network-camp-on, call-back-from-queue,
find-me, meet-me-pager, call-forwarding,
call-interrupt, call-waiting, business-dialing, automatic-call-distribution,
virtual-automatic-call-distribution,
speed-dial, call-transfer, conference-calling and network-administration.
Echo cancellation is used to eliminate
echoes caused by PSTN circuits associated with the
telephones. Silence detection is used to improve network
efficiency by not sending packets when the parties are not
speaking. The delay in the packet-switched-network is used
to adjust the size of sound segments formed into a packet.
The interfaces allow the system to provide end points in a
packet-switched network that manage a telephone call over
the packet switched network.
